For some reason when I run Ekiga it doesn't detect any v4l or v4l2
drivers...Only picture...

Does the OS detect your device? I.E:

     1. Do you see it in dmesg?
     2. Does a device get created (e.g. /dev/video0)
     3. Can you read from the device: e.g: $ ffmpeg -f video4linux2 -s
        800x600 -r 10 -i /dev/video0 test.avi

Likely your problem is one of the 3.

Apparently ffmpeg can't use v4l2 either...Perhaps there is a package
I've failed to emerge?

Note the --disable-v4l in your configuration.

Also apparently I am running a different version of ffmpeg than you are
so maybe the version you are running does not support V4L.

I assume 1 and 2 checked look fine?

Ekiga uses pwlib.  Did you enable the v4l[2] USE flag for pwlib?

That was the problem! But now I have another issue, because my
microphone doesn't seem to want to work in Ekiga ... I can get playback
through my speakers (using alsamixer) but no matter what I do I can't
get Ekiga's echoing system to echo back my microphone
(sip:500@ekiga.net) ... It's frustrating at this point in time, but I
hope this is as easily solvable as the webcam issue.

Make sure your microphone is unmuted (alsamixer).  If applicable, make
sure that your "capture device" is set to "microphone" (alsamixer -V
capture).

Nope, not working. No matter what settings I use in alsamixer the
microphone doesn't seem to work with Ekiga's echo call ... So I don't
know where to go from here. Here is a screenshot with my alsamixer
settings

I dunno... works for me ;-)

Again, check your USE flags... does pwlib have alsa support?

Yessir, it does...

dev-libs/pwlib-1.10.10-r1  USE="alsa ldap sdl ssl v4l xml -debug -ieee1394 -ipv6 -oss -sasl -v4l2"

Is there anything else I should check? Perhaps I should enable OSS
support as well...? I mean, it may work, considering I have ALSA doing
OSS emulation. I'm not sure if it's even worth a try though.

You shouldn't neeed OSS support (is it still even in the kernel?) or
even OSS emulation AFAIK.  Does arecord even work?  Start with the
basics.

No matter what I do arecord doesn't want to work, and I don't understand
how to apply the output of `arecord -L` with the -D flag ... Any ideas?
